CATCH FOR l-HNGED LANTERN=TOPS.

SPE CIPICATION forming part of Letters Patent No. 371,687, dated October 18,1887.

Application tiled March 15, 1887. Serial No. 230,5 4). No model.)

To all whom it may concern:

Be it known that i, FRANK Kiioznnoisnr, a subject of the Emperor ofGermany, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful improvement in Catches for Hinged Lantern- Tops, of which the following is a specification.

It is common at this time to lock the swing ing side of hinged lanterutops to the lanternframes by means of spring'catches made of wire and soldered atone end to the underside of the apron or horizontally projecting rim of the top, the free end of the spring forming the catch which engages with the frame. A fair illustration of this catch is found in the patent to Baron and Rufer of July 22, 188i, No. 302,465. Sometimes these catches have been secured in tubes soldered or otherwise fixed to the canopy or top, and sometimes they have been made of flat metal and riveted to the canopy; but in operating all forms of these springs, which are secured at one end and have free ends acting as catches, there is a tendency to tear the spring, little by little, from its attachment to the top, the spring acting as a lever receiving power at its free end and transmitting such power, largely multiplied, to its secured end. It will thus be seen that unless the attachments are very strong indeed the springs will sooner or later break loose, and, as a matter of fact, they do often become loose. To obviate this evil I have conceived the present invention, in which the top rim is provided with an upwardlyextcuding annular bead, in the concave under surface of which the spring portion of the catch may be inserted. This beaded portion of the rim is severed with two contiguously-located crosseuts, and the metal between such cuts is bent downward to a position and outline the reverse of the bead. The spring is now inserted in position over the bent-down portion of the head, with a portion of its length at either side of the bent-down part. resting in the under concavity of the un bent bead. The spring is thus let into and held in the metal of the rim itself, the bent-down portion acting as an integral strap to confine it against all move ment except a longitudinal one. her the tearing loose is wholly obviated and the use of solder becomes optional.

In this man In the accompanying drawings, which form a part of this specification, and in which similar letters of reference indicate like parts, Figure l is an elevation of the upper portion of a. lantern having a hinged top, to the catch of which my present invention has been applied. Fig. 2 is a vertical section upon the line 2 2 of Fig. 1. Fig. 3 is a plan, and Fig. 4. a bottom, View of the hinged lantern-top. Fig. 5 is a section upon the line 5 5 of Fig. 3.

1n said drawings, A represents the dome, and B the rim, forming the top of a lantern and hinged to the wire frameC thereof in the usual manner, the hinge being shown at c, and the elevation given in Fig. 1 being that of the swinging side.

b is an annular ridge or bead formed in the rim B, and D is the spring catch for locking the swinging side to the frame, and to which my invention relates.

The catch is provided with the usual button or deflector, d, at its free end, serving both as a button to be pressed upon when the catch is to be released and as a deflector to spring the catch and allow it to pass by the upper ring, C, of the frame when the lantern is closed. The free end passes through a slotted guide, E, depending from the rim B, and the upper wire or ring of the frame is locked, when the lantern is closed, between this guide, the under surface of the rim, and the upper surface of the catch. The parts thus far described are found in nearly all lanterns of this class.

Instead of securing the stationary end of the catch D to the under surface of the rim B by soldering or riveting it to that surface, or by any other old method of attachment, I secure it as follows: A couple of slits, a a, about one-fourth of an inch apart, are made through the metal of rim B, and preferably in the bead b, and the portion m between the cuts is bent inwardly or downwardly, as more particularly shown at Figs. 2 and 3. The catch is now inserted over the part m and under the contiguous parts of the rim, so that said part 111. is caused to act as a strap and hold the catch in its embrace, preventing any movement thereof except in a longitudinal direction. I thus devolve upon an integral part of the rim the duty of resisting the severe leverage exerted by the catch when it is opertoo hinged top the rim whereof is provided with an integral strap, m, and a spring-catch having one end secured by said strap, substantially as set forth.

2. The combination, with a lantern, of a hinged top having a bead, b, and integral strap m, and a wire spring-catch held by said bead and strap, substantially as set forth.

3. The combination, with a lantern, of a 20 hinged top having the annular bead b, severed transversely at contiguous points, with the portion between the severations bent reversely, and a spring-wire catch inserted above '1 said bent portion and under the unbent bead 25 at either side of said bent portion, substantially as set forth.
